A highly sensitive surface‐enhanced Raman scattering (SERS) platform for the selective trace analysis of persistent organic pollutant (POP) such as polychlorinated biphenyl (PCBs) was reported based on β‐CD modified gold nanoparticles (AuNPs) with the real environmental sample of polluted soil. The synthesized gold nanoparticles were characterized using UV–vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD) and transmission electron microscopy (TEM). In polluted soil the presentation of PCB is confirmed by using GC‐MS. It is further verified and confirmed by using SERS. When the contaminated soil was added to the system, the binding of soil with β‐CD resulted in the aggregation of AuNPs, and excellent Raman signal was obtained which can reflect the isomers of polychlorinated biphenyls.
